          Spring框架与持久层的整合(MyBatis)1.基本介绍Spring框架为什么要整合持久层？

因为JavaEE的开发需要持久层进行数据库的访问操作，而且使用JDBC,Hibernate(JPA),MyBatis进行持久化开发的过程中，存在大量冗余重复的代码。我们需要Spring这种设计模式对于上述的持久层框架进行整合封装。
Spring可以和哪些持久层技术进行整合？

          JavaScript中的原型原型基本概念 什么是原型？




原型可以理解成是一个东西的本质名称！

我们写的代码其实是对现实生活中的一种模拟！那么这个原型链在生活中的例子就可以是，比如只金毛犬，你可以定义他的原型是一只狗，或者是一个动物，或者是最原始的碳基生物，这些都可以是这只狗的原型，看你的需要如何去定义了.



JavaScript中的原型

          聊一聊Vue自定义指令什么是指令 Vue中内置了很多的指令，如v-model、v-show、v-html等，但是有时候这些指令并不能满足我们，或者说我们想为元素附加一些特别的功能，这时候，我们就需要用到vue中一个很强大的功能了—自定义指令。

就像vue中有全局组件和局部组件一样，他也分全局自定义指令和局部指令。
声明自定义指令全局自定义指令的创建，我们需要使用 Vue.directive(),

          Spring框架基于*AspectJ*注解的AOP编程1.使用注解创建切入点【通过之前的学习我们知道，`AOP`编程的开发步骤主要分为下面四种】



1 创建原始业务核心对象  2 额外功能  3 创建切入点   4 组装切面
我们基于注解的开发，会使我们的开发步骤变得更为简单，【2,3,4】我们会统一的放入一个切面类中去完成，因为这三部都是为了去完成一个切面的插入！

          Spring框架AOP编程下（重要AOP概念解析）1.切面的名词解释首先，在spring中什么可以组成切面？

在Spring中切面=额外功能+切入点


可以理解为，上图三个原始类中的一些方法，组成了一个切面，然后定义了一个切入点，让额外功能去插入这个切点，然后这个切面上的方法，都可以使用这个额外方法。
2.AOP的底层实现原理（动态代理原理） 【第1点】AOP如何创建动态代理类?
